Primary Outcome Measures :
  1. 2-year overall survival [ Time Frame: 2 years after study inclusion ]
    measure time of survival of each patiente up to 2 years after study inclusion


Secondary Outcome Measures :
  1. Time to relapse [ Time Frame: 2 years after study inclusion ]
    evaluate time to relapse for 2 years after study inclusion for each patient; calculate cumulative incidence of relapse

  2. Relapse-free survival [ Time Frame: 2 years after study inclusion ]
  3. Yield and purity of NK cells (CD3-CD56+) after CD3 depletion and CD56 enrichment [ Time Frame: timepoint of application of NK cells ]
  4. NK cell analysis [ Time Frame: 2 years after study inclusion ]
  5. Clinical performance (ECOG score) [ Time Frame: 2 years after study inclusion ]
  6. Incidence and severity of GVHD [ Time Frame: 6 months after start of treatment ]
  7. Incidence of (S)AEs [ Time Frame: 5 weeks after start of treatment ]

Criteria

Inclusion Criteria:
